FEED-WATER HEATER AND PURIF'IER.

No. eze, 109.

Speo'iilcation of Letters Patent.

Patented June 29, 1909.

Application tiled July 6, 1908. Serial No. 442,243.

To all whom it may concern:

Be it known that I, J osnrn Winamp Gaiman, a citizen of the United Sintes, a resident of and whose post-ollice addi-css is No. 3251 North Sixteenth street, in thv city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented mrtain new and nsef I nnn'ovcments in Feed-Vater Heaters and Purihers, of which the Following is, taken in connection with the accompanyingdrawings. a conciso and complete description thereof.

My invention coniprchends specifically the combination of one or more feed water heaters with an extension or storage tank and pressure revulatinof means intermediate thc same for hiking t ie Strain due to the pres` sure created within the feed water hea-ter from the storage tank, or preventing; such pressure from being exerted on the tank. Referring to the accompanying drawings, in which like numerals indicate like part-s throughout, Figure 1 representen heater and extension or storage tank, in side elevation,

uipped with one forni of my invention. Fi 2 is a top lan View showing u plurality of eaters wit i a common storage tank.

Referring in detail to the drawings. 1 indicutes a feed water heater of tlnwell known open ty c in which the supplied raw water is breng it into physical contant with the supplyI of exhaust steam.

flindicates a. dividing box which distributes to the heater units (where a plurality are used) a proper and uniform supply ot the raw water.

5 indicates a raw water supply pipe connection having therein a float actuated valve which is controlled by a `float within the oat chamber -7- by and through intermediate mechanism 9- indicates a suitable vent pipe. and -10- an overow for the extension tank.

Connecting the feed water heater -1- with the extension tank -8, I provide pipe connection -11 which is water scaled. This water seal connection com rises a per pendicular pipe, which is flipper or reversed upon itself, one end connected with the feed water heater, ,and the other end connected with the extension tank as shown. The length of the water seal connection is proportionate to the amount of pressure carried within the heater units.

llindicates a gate valve in the leg, connected with the extension tank, which is adapted to shut oil the eonnnunication themwith.

IBF- indcates a pipe connection connecting one of the heater unite with the Water scaled pipe connection -1l at -11l-.

l5- iudicates the outlet 'from the exten sion tank, said outlet being controlled by a suitable gate valve -1('. The outlet )ipe -l' is connected with a pipe -17- w iich conveys the treated water to toed pumps or other points of use.

An auxiliary outlet 11- to the water sealed pipe connection -llis provided, which connects it with the feed water pi )e -1-, and is for the purpose of direc y feeding the water from thc heating iuiit to tend pumps or other points of use when it is desired to utilize the water without passing it in to und drawing; it from the storage tank. A vulve, 11,- is provided in feed pipe 17 to control the passage o'f the Water from the pipe connection 1ltherethrough.

By employing` the water sealed connection 11" I am able to construct the extension or storage tank of lunch lighter material than the heater units themselves, as the strain that would be created by reason of the pressure carried within the heater units is thus relieved or taken oil' the storage tank.

Where I have uned the word separate I do not necessarily mean that the storage tank is away o apart from the heater. n the contrai' the saine may be separate, but yet in physical contact with one another.

While I have shown n single extension or storage tank connected to a heating unit or a plurality of heating units, I would have it understood that I am not limited in this respect, ne it is. manifest that a. plurality of extension or storage tanks operating in connection with a plurality ot heating units muy be employed, without departing from the spirit and scope of my invention.

I would further have it understood that I ani not limited to the particular arrangement, size, desi in, or construction of the apparatus constituting my invention as described, as the same may be altered or changed, and still come within the scope and tenor of my claims.

l-l'aving thus described my invention, what I claim as new herein und desire to protect by Letters Patent, is:

1. The combination of a water heater and tank; an exterior passage between the same; and a pressure regulating means in said passave intermediate the heat-er and tank.

2. he combination of a water heater and a tank; a water sealed conduit exterior of and intermediate and connecting the same. 3. The combination of a Water heater and a tank; an exterior passaoe dipped and reersed upon itself intermec' ing the same, and means therein for regulatinfr the fiow therethrough.

4. 7he combination of a Water heater and a tank an extension U shaped; Water sealed passage intermediate and connecting the same, and means for regulating the flow therethrough.

5. The combination of a plurality of heating units; a tank; and an intermediate exteriorly arranged passage connecting said heating units and tank; and means comprising a dipped Water sealed pipe operating to prevent the transmission of strain or pressure from the heater to the tank.

6. The combination of a plurality of heating units; a tank and an intermediate exterior passage connecting said heatin units and tank; and means operatin to ta ze excessive strain or pressure o' tie extension tank.

7. The combination of a plurality of heatiate and connecting units; a fioat controlled raw Water supply; means for efecting the equal distribution of said raw water supply to said units a storage tank; an exhaust steam supply for each of said heater units; and pressure regulating means intermediate the said heater units and said tank.

8. The combination of a heating unit; a storaee tank an outlet therefor, a Water sealeda passageway intermediate and connecting said heating unit with said storage tank and an auxiliary outlet from said water sealed passageway connecting with said outlet to said storage tank.

9. The combination of a plurality of heating units; a raw water supply and a steam supply a distributing box for eiectinr an equal cistribution of raw water to each of the heating units; a storage receptacle and a water sealed aussage, intermediate and connecting the ieating units with said storage tank.

10. The combination of a heating unit; a tank; and an intermediate exterior passage connecting said heating unit and tank, and means operating to take excessive strain or pressure off the extension tank.
